Robbie Peralta has become the latest UFC fighter to test positive for marijuana use, the promotion announced.

Peralta was found to have marijuana metabolites in his system after an April fight vs. Akira Corassani in Sweden. He lost the fight, falling to 2-1 in the UFC and 16-4 overall.

“The UFC organization has a strict, consistent policy against the use of any illegal and/or performance-enhancing drugs, stimulants or masking agents,” the UFC’s statement read.

Peralta will be suspended for six months retroactive to the date of the card, and must complete drug rehabilitation classes prior to being allowed to compete again inside the Octagon.
